Hello everyone, I am upgrading my system and I had some troubles and decided to register here to ask you guys. So I'm going to buy:

16 gb 1866 MHz Patriot RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

MSI R7870 Twin Frozr 2GD5/OC :http://www.newegg.com/Product/Product.aspx?Item=N82E168...

(COMBO)AMD FX-8120, MSI 990FXA: http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...

I was thinking of buying these but my PSU don't support PCI-Ex 3 and there is only PCI-Ex v2 and a PCI-Ex v1 output so I think I need a PSU too or maybe another motherboard. btw my chasis is ATX (just to let u know). And what is this modular stuff about the PSU i see them all the time when i search. Anyways, thank you for reaading so far and anybody with a hardware suggestion?(please dont tell me to buy intel or nvidia cuz i REALLY want this gou and intel is overpriced when compared to AMD) my budget is around $700 (i think i wont buy 16 gigs of ram actually i will buy 8 gb i dont think it'll be useful i just want to play bf3 like games on ultra+ MSAA on full hd)

Trust me, Intel isnt overpriced, its priced for its awesome performance and generally does better than AMD. Anyways any quad core will do well on BF3 and a decent GPU too. And yes, that RAM is too much for gaming, also dont get speed higher than 1600. Simply not worth it. PCIe 3 is an updated version of PCIe2 and its faster. Modular means that the cables are easier to manage for some reason xD (not good in PSUs.)

The PSU doesn't need to be "compatible" with PCI-e 3.0. PCI is the interface by which expansion cards communicate with the rest of the computer, you wont be connecting the PSU to a PCI slot.

Any PCI-e slot can take any PCI-e card. For example PCI-e 3.0 GPU on a PCI-e 1.0 motherboard will work.

Modular means the cables can be disconnected from the PSU itself, it results in less clutter in the case since you can chose the cables you need, but are more expensive for a good quality modular PSU.

I am going to tell you to go Intel, because they are not over priced when compared to a 8120 and you will get far better performance from a 2500k or 3570k.

The GPU is fine, very nice card, good price.

Get 8GB of RAM instead, you won't need 16GB for gaming, not even close.

Well... thank you! but can u suggest me a product or can u give a link? allright i will be buyin 8 gb 1600 MHz RAM but do i need a pci-e 3 motherboard? i mean does the bandwith limitation limit my fps? (i mean pci-e 3 card on pci-e 2 mobo) or can u please give an intel (pls not more than $ 180-190) and a pci-e 3.0 mobo if needed? thank you again ;)

I suggest Corsair Vengeance 8GB RAM (2x4GB) and Intel Core i5 3550K/2500K.
For a mobo, probably an Asus/Gigabyte Z77. I dont really use newegg, so yeah. No links, sorry. :(

guys i searched inel and when i saw the processors priced $1000 i just closed the tab :heink:  and i entered http://pcpartpicker.com then started building + doing some little researches and i made a new pc:

CPU: Amd Phenom II x6 1100t

MOBO: Asus ROG Crosshair V Formula ATX AM3+ Motherboard

RAM: Patriot Signature 8GB (2 x 4GB) DDR3-1600 Memory

GPU: MSI Radeon HD 7870 2GB Video Card Twin Frozr 2GB/OC

(i was gonna buy a new PSU too but... I think i will do it later cuz i dont think i can convince my father to buy a new 700 W CF ready $100 PSU i will use my 600 W OCZ psu)
And it's all around $710 !!!!!

No Intel processors cost $1000. That must be a premade PC WITH the Intel processor.

First, dont judge anything by price. That processor is i7 3960X which is a very high class processor, its six core, uses a more recent socket, and has alot of processing power. Do you see now? :D  You can buy an i7 3770K for $300 actually. :/  Actually, an i7 is too much for gaming now a days. Look at this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Microcenter - if you have one nearby - has i5 3570k + ASRock Z77 Motherboard for just under $300 AFTER tax. Only catch is you have to go to the store and pick them up. Great combo ... add a 120 GB (min) SSD and you'll be happy and cranking out FPS like a pro ! Good Luck !!

GPU: MSI Radeon HD 7870 2GB Video Card Twin Frozr 2GB/OC ---->(actually i might wait for the sea islands)
